LOADING AND UNLOADING MACHINE.

Application vfiled July 19,

T 0 all whom it may concern:

especially adapted for automatically and mechanically transporting ortransferring hides and skins, and for charging and dischargingreceptacles with such hides and skins, such as tanning machines, dyevats, drying lofts, etc.

The invention is designed primarily for the purpose of providing a newstep in the j" through the machine, carrier. and hide sup-v handling ofhides and skinsduring the process of tanning, and especially for the.

purpose of eliminating hand. labor, to a great extent, in which thelaborers are ex posed to a tiresome and unsanitary work, thusreducingimmensely the cost of labor and production of tanned materials.

The invention mechanically considered consists essentially of a mainportable truck, for conveying or transporting skins and hides from placeto place for various treatments during the process of tanning, and alsocontemplates an elevator structure on the truck upon which'an auxiliarycarriage or carrier is movable, and an extensible track way by which thecarrier may be projected to proper position where a hide-sup portingmember carried by the carrier may be either loaded or unloaded fromthecarrier as the case may be, andthe invention further consists incertain novel combina tions and arrangements of parts as will behereinafter more fully described Q and claimed. v.

' In the accompanying drawings I have illustrated one complete exampleof the physical embodiment of my invention, constr'ucted and arrangedaccording to the best mode I have so far devised for the practicalapplication of the principles of my invention, and while I shallhereinafter refer to the device in connectionwith the handling of hidesand skins, it will readily be understood that other articles or objectsmay be handled equally well by the machine.

In the preferred form of the invention as illustrated in the drawin s,the portabletruc'kis made up of a metallic horizontalbase frame 1fromwhich rise the two. pairs of up-' right corner posts 2 and 3. Theupper ends of these posts 2 and 3 are connectedin pairs bvlongitudinally extending side arms '4! and members of the frame wherethey are supported nbearings 8, and at theupper end of the frameadditional bearings or bracln ets 9 are provided so that these screwbars tudinal sides of the truck frame, being supported in journalbearings 19, and the driving shaft is coupled to the countershaftsthrough the bevel gears 20 and 21, the gear couples being located at theends of the driving shaft vasloest seen in Figure 6, Each countershaftis provided with a pair of worm screws, as 22 23, and these respectiveworm screws engage the worm wheels 291, four in number and one eachfixed on a screw bar or upright threaded post 7, so that when j thedriving shaft is actuated thetwo coun ter sliafts impart rotary motionto the screw bars through the medium ofthe bevel gear couples and thescrew couples as described. 7

Through the rotation of these four screw bars the elevator is operated,and this elevator comprises a frame, open at its front,

7 horizontally disposed, and preferably'of fiat metallic side bars25,having at the four corners of the rectangular shaped frame the fixednuts26 each threadedfor a screw bar 7, and each firmly bolted or rivetedto the elevator frame. Thus it will readily be seen that when these fourscrew bars are revolved in unison, the elevator will be lifted or low-,ered, depending upon the direction of rotation of the screw bars.

The two bars 25 of the elevator frame form rails or tracks, positioned,always, in a horizontal plane, and anupwardly inclined, fixed rail 26'forms a continuation or extension ofeach of these rails, these inclinedrails being riveted or bolted to the horizontal side rails of theelevator, and, of course'the "fixedrails or inclined ra ls move bodilywith the Y horizontal rails as the'elevator is operated,

The rails may be elongatedQand to accomplish this purpose I provide anextension rail 27'for each of the inclined rails 26', the extensionrails being adapted to telescope or slide within grooved guidewayslocated at the inner sides of the inclined rails 26, and each providedwith a horn or-bumper 28 at its extreme end. The slide railsoriextension rails are projected from the stationary rails of theelevator by means of a' pair of hains 29, one at-each side of theelevator,

. end arms 4-6 and sharp pins or studs l7,

platform 35 which joins the side bars 25 of the elevator, at the rear ofthe machine. The drums may be revolved from the driving shaft 36 throughsprocket gearing indicated at 37 in Figure 11 from aconventi'onal clutchmechanism shown in said figure, to wind the chains on the drums, and thewinding of the" chains of course draws the carriage; as to the right, inFigure 2. The carriage is provided with four wheels arranged in pairs38,38, on axle 39, and 4:0, 10 on axle 11." Thus when the slide rail isprojected, or rather when the carriage is made to project the rail, thewinding of the chain on the drumlfirst draws the carriage along therails 25, 26 until the front wheels 40 encounter the horn shaped bumpers28 and ride up onv them assh'own best in Figure 2, then the continuedpull of the chains causes the extensible frame for rails 27 to slideupwardly and outwardly, vith the wheelstl supported on the bumpers andthe wheels 38 rolling over theinclincd rail 26 until'the extensiblerails and 'carriagereach the projected positi'on iirFig ure2. U1The'carriage 31 is joined at the front the cross arms 42 and at the rearby the cross brace 43, and it will be understood that the axle 39 at therear may extend across from side bar to side l ar of the frame, buttheaxles for wheels 410 are stuh' axles' ll in the 'I'CSpGC't UQ, side barsof. thefriaiiie, so; that a hide or skin 44: may be carried betweenthese, side bars of the carriage frame. The hides or skins are supportedon a suspending mem her which I shall terma carrier, which com prisestwo end brid 45, (t5 formeduvith V A and, between these two hriogesarefsup o'r ed plurality of suspension bars or rods 48 each of wl'iichis so'cketed to fit over the pin's on the bridges, and tho hides .o Vpended 'lrom these rods orbais. Thel res 45 of the carrier are ri 'dlysupported on the can 31, and the suspension bar as illusii ted in ligure' 20f thedrawi are designed to be suspended inithe rota barrel 19forming p rt of atanniiig in chi One head of the ha i i of the projectedmachine, and both heads of" tlioflharrel are provuiled with supportingmeans so that the bars 18 may be suspended longitudinally'of the barrelat the inner pe: riphery thereof, andwhen the barrel i s'rotatedthehides or skins on the bars l8 are carried bodily around with the barrel.The: machine of the invention isso constructed" that it "will manipulatethe carrier susslrins 'are sus-l el isopen for admission" by V pend thehide supporting bars in the rotary barrel. .Thefirst part of theoperation has been accomplished in full lines in Figure 2,

and the forward ends of thebars 48 are supported on a ring 50 at thedistal endof the arrel, while the second part of the movement isindicated in'dotted'lines in Figure 2, where the-bars are supportedbetween the ring 50 and a similar ring 51 at the proximate end of thebarrel. 1

..Th proximate end of the carrier is'lifted from position in fulllinesFigure 2 by' a' pair ofllifting'jackssupported on the ele-' vator,which acksv lift the carriage, or rather one end of thecarriage andswing it upwardlyon the Wheels 40 as pivot points.

These lifting jacks are operated in unison from the-driving shaft 36' atthe rear of the "ions 60 on the vertical-screw bars 61. supported inbearings 62 on1a leg 63 ofthe elevator;v On'each'screwbar is athreadednut '64 formed with: an' arm 65 which supend each lever is provided witha hooked or curved-seat 68 adapted to engage up under the two ends ofthe axle 39 of the carriage. Now when the jacks are operated asdescribed it will readily be seen that the carriage will be swung on thefront wheels as a pivot, the forward end being lowered and the rear endlifted so that the proximate ends of the hide bearing arms are liftedand moved endwise into place as before indicated. The hide bearing armsare of proper length to permit endwise shifting when they are beinglifted above the bars 50 51, and are of suitable length to rest on saidbars. In order to withdraw the projected part of the machine from thebarrel, the jacks may be lowered, or the elevator may be bodily lowered,the carriage permitted to run down its inclined tracks and the extensionor slide frame withdrawn or retracted, as by a pull chain, not shown.

In Figure 4 the machine is manipulating the hides and their carriers sothat the hides are suspended in a loft, between the two horizontalsupports 69, 70, the operation, however, being practically the same aswhen the hides are placed in th barrel or receptacle of the tanningmachine for treatment.

In Figure 9 a sectional form of the hide supporting bar or rod isillustrated, this form also being shown in Figure 5; Here the lowersection 71 has sockets 72 to fit over the pins or'studs 47 on the brid eand the intermediate section .73 has doub e end spikes 7 4 projectingfrom its top and bottom to engage sockets 7 5 in the lower section andsimilar sockets, 7 6 in the uppersec'tion. The

hides or skins are suspended from the barsas indicated in Figure 5,being retained between the upper section' and intermediate section andthe lower section and intermediate section respectively.

The carrier which supports the brindl of hides. or skins may be ofvarious constructions, andthe useofthe machine may be variedgreatly,b,ut thegoperation remains the same, and :while I have describedthe n'iachine in connection with the treatment of hides, it will readilybe understood that Changes may also be 'made in thecon-..

struction of the machine, within the scope: I

of my claims-without departingfrom the spirit of my invention, and allsuch changes are contemplated. e

In operating the machine in the process of treating hides and skins,withthe loaded carrier supported on the carriage, the apparatus isbrought-toposition of Figure 1, ready toisuspend the carrier and itshides in the tanning machinebarrel 49. The ele- V j V vator is lifte'dto the position indicated in I ports a lifting lever-=66 that r isslidable 1n J bearings 67 on the elevator, and at its upper.

by the movement of both the elevator andthe projecting apparatus, thatthe upper ends of the hide supporting bars are located in theirsuspension devices in the barrel, and then the lower end of the carriageis tilted upwardly by means of the elevating acks so that the proximateends of these hide supporting bars are emplaced, as shown in dottedlines Figure 2. After the carrier has been properly deposited, the jacksare lowered, the carriage will roll down its incline, and then thecarriage and extensible frame are retracted.

No claim is made herein to the particular form of carrieror hidesupportingbars, nor

to the special manner of loading tanning mato desired position, as forinstance, a flat suspension or a folded one, or partly suspended, orhose shape, a single hide or a whole pack, with the hides and skinsoverlapped at their bases, or enveloping such hides and skins in such abag form as may' be designed by the operator. -What I claim is l.
